Here is a hack that displays quota on a server not supporting quota, like dovecot or any mail server without using the built in quota feature(If you find this simpler). Edit your /etc/sudoer, add the following lines. Replace apache with whatever your httpd/apache user is. RHEL/Fedora user is apache. <code type="bash"> apache ALL = NOPASSWD: /usr/bin/du apache ALL = NOPASSWD: /bin/ls </code> create a folder 'quota' on your server '/' partition <code type="bash"> mkdir /quota </code> to assign quota to any user <code type="bash"> echo "10000" > /quota/username </code> This would give 10MB quota to a user. Give whatever you wish to assign. Create the following file /var/www/html/horde/quota.php <code type="php"> <?php { $user=Auth::getAuth(); $usage = `sudo du -s /home/$user/mail | cut -d "/" -f 1` + `sudo du -s /var/spool/mail/$user | cut -d "/" -f 1`- $archive; $archiveused = round($archive/1000);; $usedmb = round($usage / 1000); $quota = `cat /quota/$user`+ 1; $quotamb = round($quota / 1000); $percent = round($usage * 100 / $quota); if ($quota > 1) { echo '<table width="100%" border="0" cellpadding="0" cellspacing="0"><tr><td class= "item"><table border="0" cellspacing="0" cellpadding="0" width="100%"><tr>'; echo '<td align="left" class="header">Login: ' . $user . '</td>'; echo '<td align="right" class="header">'; echo "Quota Used $usedmb MB of $quotamb MB ($percent %)"; echo '</td></tr></table></td></tr></table>'; } if ($percent >= 100 && $quota > 2) { echo '<script language="JavaScript" type="text/javascript"><!-- alert("QUOTA EXCEEDED, DELETE EMAILS TO CONTINUE THE USE OF EMAIL FACILITY") // --> </script>';} if ($percent >= 80 && $quota > 2) { echo '<script language="JavaScript" type="text/javascript"><!-- alert("You are nearing your mailbox quota limit, please delete & purge emails to avoid any inconvinience.") // --> </script>';} } </code> Change the above reflecting your mailserver's folder locations. Above is for dovecot on RHEL 3, with mails in /home/username/mail and /var/spool/mail/username. Add this in horde/imp/templates/common-headers.inc (line 27, 28,29) <code type="php"> $page_title = $GLOBALS['registry']->get('name'); if (!empty($title)) $page_title .= ' :: ' . $title; if (!empty($refresh_time) && !empty($refresh_url)) { echo "<meta http-equiv="refresh" content="$refresh_time;url=$refresh_url" />n"; } Horde::includeScriptFiles(); ?> <title><?php echo htmlspecialchars($page_title) ?></title> //--->Add the following here <---- <?php include_once HORDE_BASE . '/quota.php'; ?> //---end--- <link href="<?php echo $GLOBALS['registry']->getImageDir()?>/favicon.ico" rel="SHORTCUT ICON" /> <?php if (isset($mailbox_url)): ?> </code> Do let me know if this was useful or send in any improvements/suggestions. jigish dot gohil at gmail dot com
